摘要：Problem to be solved: to provide an optical member capable of maintaininghydrophilicity for a long term in the environment where the siloxane contamination existsin the packing storage form and the outdoor exposure environment. Further, an opticalapparatus having excellent anti fog property is provided. Further, a method ofmanufacturing an optical member for manufacturing the optical member is provided.Base material andAn optical member having a porous layer on the substrateThe porous
layer has silica particlesA silanol group having silica particles on the surface of the porouslayerA functional group of divalent organic groups having a specific number of atoms anda specific hydrophilic group is substituted forTo the silanol group on the surface of theporous layerAn optical member whose molar ratio of the divalent organic group (divalentorganic group \\/ silanol group) is greater than 0.25 and less than 1.5.Optical device havingsaid optical member.A method of manufacturing an optical member having a basematerial and a porous layer on the substrate has a coating liquid application step, adrying curing step, and an organic strand substitution process.Diagram
